If the near-point distance of the jeweler is 22.0 cm, and the focal length of the magnifying glass is 7.70 cm, find the angular magnification when the diamond is held 5.68 cm from the magnifying glass. Assume the magnifying glass is directly in front of the jeweler's eyes.

The angular magnification M = 2.1

Explanation:

If the jeweler holds the diamond at the focal point of the magnifying glass, its image will be produced infinitely far away.

This gives an angular magnification of M = N/f

Since the diamond is held 5.68 cm from the magnifying glass,

Then, M = (N - 5.68)/f

Where N = 22.0 cm and f = 7.7 cm

M = (22 - 5.68)/7.7

M = 2.1

he . if i may ask what i your question exactly?

explanation:

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )
